Here's some tips to get perfect:
1.Feel calm, you can always restart.
2.Go on a server with very little people and be muted in chat to reduce lag.
3.Listen to the beat of the music. (Have you noticed you usually do better on the songs you like.)
4.Be patient, you usually never get perfect the first time you try. Some took me to play like15 times to get a perfect.
